The ruling comes on the heels of the accountability board’s announcement in December that names like Mickey Mouse and Adolf Hitler were being counted as valid names on recall petitions, so long as they were properly dated and accompanied by a Wisconsin address.

Kevin Kennedy, the board’s general counsel, said during a hearing at Waukesha County court that entering the recall signatures into a database to look for duplicates could take eight extra weeks and cost close to $100,000, according to the Sentinel.

But attorneys representing Walker and other GOP officials being threatened by recall efforts presented to the judge instances in which one person reportedly signed the recall petition multiple times, or fictitious names such as Bugs Bunny were accepted as valid, the Sentinel said.

Judge J. Mac Davis ordered the accountability board to take “reasonable” efforts to eliminate problematic signatures, such as duplicate and fictitious ones, saying in his ruling, “Counting the signature of Bugs Bunny is something only lawyers could try to make seem OK.”

Walker said earlier this week that he expects organizers to collect more than the 540,000 signatures needed to force an election, predicting one to occur in early June.
